ObjectiveTo investigate the association between insulin resistance （IR） and cardiovascular metabolic indicators， including blood pressure， blood lipids， and serum uric acid， in a middle-aged population. MethodsBased on the baseline survey of the Hong Sifang cohort of China National Salt Industry Group， a total of 575 participants were included. According to the homeostasis model assessment of insulin resistance， the participants were divided into an IR group （n=116） and a non-IR group （n=459）. Differences between the two groups were compared using the t-test and chi-square test. Multivariate logistic regression analysis was performed to evaluate the associations between IR and abnormalities in metabolic indicators. ResultsA total of 575 participants were included， including 390 men and 185 women， with a mean age of （48.58 ± 5.14） years and a mean body mass index （BMI） of （24.16 ± 2.97） kg/m². Blood pressure， serum uric acid， and blood lipid levels were significantly higher in the IR group than in the non-IR group （P<0.001）. After adjusting for potential confounders including age， sex， and BMI， IR was independently associated with hypertension， dyslipidemia， and hyperuricemia， with odds ratios （OR） and 95% confidence intervals （CI） of 2.57 （1.61-4.09）， 3.81 （2.36-6.17）， and 2.68 （1.53-4.71）， respectively （all P<0.001）. ConclusionInsulin resistance is significantly associated with multiple cardiovascular metabolic risk factors in the middle-aged population. Monitoring IR may contribute to the early prevention and control of cardiovascular diseases.

Objective To investigate the efficacy of preoperative nebulized indocyanine green (ICG)-assisted thoracoscopic anatomical lesion resection (TALR) in treating pediatric congenital pulmonary airway malformation (CPAM). Methods A retrospective analysis was conducted on clinical data of 45 children with CPAM who underwent thoracoscopic surgery at the Third Affiliated Hospital of Zhengzhou University between June 2023 and March 2025. The patients were divided into an ICG group (preoperative nebulized ICG 0.5 mg/kg+TALR) and a non-ICG group (TALR under white light), with perioperative and postoperative recovery parameters compared between groups. Results A total of 45 children [22 males, 23 females; median age 7.4 (1.1-75.0) months] were enrolled. The ICG group (n=22) and non-ICG group (n=23) both achieved uneventful recoveries. Compared to the non-ICG group, the ICG group demonstrated significantly shorter surgical duration [91.3 (38.0-144.0) min vs. 100.0 (50.0-175.0) min, P=0.032], reduced intraoperative blood loss [3.0 (2.0-10.0) mL vs. 5.0 (1.0-10.0) mL, P=0.049], shorter postoperative drainage duration [2.7 (1.9-3.9) d vs. 3.4 (1.8-19.9) d, P=0.003], and shortened hospital stay [4.6 (2.9-9.8) d vs. 5.0 (3.9-21.5) d, P=0.013]. Residual lesions occurred in 2 patients from the non-ICG group but none in the ICG group. Intragroup comparisons revealed significant improvements in ratio of time to peak tidal expiratory flow to expiratory time, ratio of volume to peak tidal expiratory flow to expiratory volume, and tidal volume per kilogram after surgery in both groups (P<0.05), though intergroup differences showed no statistical significance (P>0.05). Conclusion Preoperative nebulized ICG administration facilitates lesion identification in CPAM, reduces technical difficulty of TALR, enhances therapeutic outcomes, and provides valuable assistance for performing TALR procedures.

Objective To observe the value of immediate CT-guided small negative pressure thoracic drainage for pneumothorax after percutaneous lung biopsy(PTLB).Methods Totally 172 patients of unilateral pneumothorax after PTLB were retrospectively enrolled,including 83 patients underwent immediate CT-guided small negative pressure(about 30 mmHg)thoracic drainage after PTLB(group A)and 89 patients underwent bedside closed thoracic drainage after PTLB(group B).Clinical data before treamtent,degree of pneumothorax,the duration of catheterization,pain degree during catheterization(visual analogue scale[VAS]),blood oxygen saturation after treatment,the ratio of immediate relief of clinical symptoms,duration of drainage retention,duration of hospitalization after treatment and the occurrence of pleural reaction were compared between groups.Results Drainage went smoothly in both groups.No significant difference of clinical data before treatment nor pneumothorax degree was found between groups(all P＞0.05).Compared with those in group B,the duration of catheterization was shorter,and pain degree was lower during drainage in group A(both P＜0.001).After drainage,blood oxygen saturation and the proportion of immediate relief of clinical symptoms in group A were both higher than those in group B,while the duration of drainage retention and hospitalization were both shorter in group A than those in group B(all P＜0.001).Pleural reaction occurred in 2 patients in group A and 1 patient in group B,and no significant difference of pleural reaction was detected between groups(P=0.520).Conclusion Immediate CT-guided small negative pressure thoracic drainage was effective and safe for pneumothorax after PTLB.

OBJECTIVE To explore the mechanism of action of Fushao Diqin Decoction in the treatment of colorectal cancer.METHODS In vitro cell experiments were conducted using Fushao Diqin Decoction to treat colorectal cancer CT-26 cells,and the cell proliferation and migration abilities were detected.Flow cytometry was used to detect the levels of reactive oxygen species(ROS)in colorectal cancer CT-26 cells,as well as the levels of iron ions(Fe2+),malondialdehyde(MDA),and the activity of su-peroxide dismutase(SOD).PCR Array and Western blot methods were used to analyze and verify the differential gene expression of ferroptosis.Balb/c mice were randomly divided into a blank control group,a model group,an oxaliplatin group(1.5 mg·kg-1·d-1),a low-dose group of Fushao Diqin Decoction(4.49 g·kg-1·d-1),a medium dose group of Fushao Diqin Decoction(8.97 g·kg-1·d-1),and a high-dose group of Fushao Diqin Decoction(17.94 g·kg-1·d-1)for in vivo animal experi-ments.The effects of Fushao Diqin Decoction on Fe2+,ROS,MDA levels,SOD activity,and Nrf2,Keap1,SLC7A11 and GPX4 ex-pression levels in mouse tumor tissues were tested.RESULTS In vitro cell experiments showed that compared with the blank control group,Fushao Diqin Decoction significantly inhibited the proliferation and migration of colorectal cancer CT-26 cells in a dose-de-pendent manner.Fushao Diqin Decoction could increase the Fe2+content(P＜0.05)and ROS level(P＜0.01)in colorectal cancer CT-26 cells,increase the MDA level in CT-26 cells of colorectal cancer(P＜0.01)and significantly reduce SOD activity(P＜0.01).Iron death PCR array analysis found that compared with the blank control group,after intervention with Fushao Diqin Decoc-tion,the expression of genes GPX4 and SLC7A11 was significantly downregulated,while the expression of GSTA1,HMOX1,Ca9,Chac1,Keap1,Sqstm1,NOX1,FTH1,Tfr1,SAT2,Pparg,and Hamp was significantly upregulated.Western blot analysis revealed that after intervention with Fushao Diqin Decoction,the expression of Keap1 protein was upregulated(P＜0.01),while the expression of Nrf2,SLC7A11,and GPX4 proteins was downregulated(P＜0.01)in colorectal cancer CT-26 cells.The results of in vivo animal experiments showed that Fushao Diqin Decoction significantly inhibited the growth of subcutaneous transplanted tumors in mice(P＜0.05),increased the degree of tumor tissue necrosis,and levels of Fe2+,ROS,and MDA(P＜0.05,P＜0.01),decreased SOD ac-tivity(P＜0.01)and upregulated Keap1 protein expression(P＜0.01),while downregulated Nrf2,SLC7A11,and GPX4 protein ex-pression(P＜0.01).CONCLUSION Fushao Diqin Decoction has an anti-colorectal cancer effect and may promote ferroptosis in colorectal cancer cells by inhibiting the Nrf2/SLC7A11/GPX4 signaling pathway to exert its anti-colorectal cancer effect.

Objective:To explore the effect of the mucin modulator Talniflumate (Tal) on breast cancer cells and its synergistic effect after combined with the chemotherapy drug paclitaxel (PTX).Methods:The breast cancer cells were cultured in vitro. Lymphocyte proliferation activity assay (MTS) was used to detect the effects of different concentrations of Talniflumate alone and paclitaxel on the survival rate of breast cancer cells. The effects of the above drugs on the apoptosis of breast cancer cells were detected by flow cytometry. Western blot was used to detect the expression of glucosamine transferase (GCNT3) (the target of Talniflumate) in breast cancer cells before and after the treatment with Talniflumate. Transcriptome sequencing clarified the changes in related signaling pathways after treatment with Talniflumate. Results:Talniflumate promoted the apoptosis of breast cancer cells MCF7 and MDA-MB-231 cells in a concentration-dependent manner. The combination of Talniflumate and paclitaxel had a significant synergistic killing effect in MCF7 cells but not MDA-MB-231 cells. Western blot indicated that GCNT3 was highly expressed in MCF7 cells, while almost no expression in MDA-MB-231 cells; Talniflumate could reduce the expression of GCNT3 in MCF7 cells and after combined with paclitaxel, the expression of GCNT3 was downregulated more significantly. Transcriptome sequencing suggested that Talniflumate can regulate the expression of multiple signaling pathways such as TNF, p53, and SNARE.Conclusions:Talniflumate could induce apoptosis of breast cancer cell. Talniflumate combined with paclitaxel has a significant synergistic effect in killing tumor cells in breast cancer cells with high GCNT3 expression such as MCF7. The mechanism of Talniflumate induce apoptosis of breast cancer cells may be related to multiple signaling pathways such as TNF, p53, and SNARE.
